Recommended Posts

first of all im in the middel of changing the turbo's on my 94 j spec and have found a pipe thats not connected to anything ...

 

if you are looking at the turbos from the front of the car, on the first turbo you u can c there is a pipe coming out of it on the top right hand side of it ... just wondering where this pipe should be connected to ???

 

also while doing this and removing al the pipework that runs along the top of the turbos i have found a lot of oil in these pipes ... im hopingthat this is also just a sighn that the turbo's have had it ???.. it would explain why i have been getting a lot of oil through the dumpvalve

 

any help greatly appreciated ...

Sounds like the pressure reference for the wastegate actuator. Is it on here?

yes thats the cookie .... .would it be disconnected as part of a cboost controler installation? if not where does it need plugging bak into?

 

You run a hose from it to your boost controller solenoid, and then the return hose from the BC to the barb going into the top of the actuator. The barb coming out the front of the actuator that points downwards it the one that gets blocked off with an aftermarket boost controller install.
